INICATOR FOR AUTOMOBILE-RADIATORS.

Application led April 30, 1918. Serial No. 231,690. v

Be it known that I, WALTER Gr. CRAMER, of Cincinnati, in the county of Hamilton and State of hio, have invented certain new and useful Improvements in Indicators for Automobile-Radiators; and I do hereby l declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to devices adapted to be attached to tanks for indicating the quantity of fluid in the tank. rIhe object of my invention is to provide a simple and highly efficient device which is particularly adapted for use in connection with radiators of automobiles to show whether or not it is necessary to add additional Water, the device being formed of a minimum number of parts so..assembled as to not readily get outI of order. 4

In the drawings, Figure 1 shows in per- To all whom t may concern:

spective a portion of an automobile radiator with `my device attached thereto. Fig. 2

is a vertical sectional view; Fig. 3 is a perspective of the mec anism of my indicator.

At 1 I have .sho n an automobile radiator of conventional form provided with the usual opening through which water is supplied and which opening is closed by a cap 2. This cap has a central aperture 3 to receive the lower portion of a vertically disposed tube 4 which is held in place on the cap by a laterally extending ange 5 of the tube bearing upon the exposed face of the cap and the nut engaging a threaded por.- tion Z of the tube on the other side of the cap. The upper end, of the tube 4 supports a housing 8 which I havel shown of annular form and as having a f-ront face 9 and a rear face 10 each of which is covered by`\a glass disk 12. These faces form dials and.v

are provided with any preferred lettering or other markings to indicate the amount of fluid which has been consumed or the amount which is present in the radiator.

Located between the dials 9 and 10 and having their bearings in such dials are a 5@ drum13 anda shaft 14:, the ends of thelatter extending beyond the dials and carrying indicating hands'l and 16 which travel over' the-markings on'the dials. Fixedly secured on tlfe shaft 14: is a gear 17 which is adapted to mesh with a pinion 18 yon the spindle 19 of drum 13,'the spindle being supported by the two dials before mentioned..

A flexible member 20, of cord or other material, is adapted to be wound upon this rdrum, one end of the flexible member being secured to the drum and the other end passed through lthe tube l and having a ioat 21 attached at its extremity.` The drum 13 is so disposed within the housing 8 that as soon as any portion of the iiexible member is unwound from the drum, due to a lowering of the float in the tank, it will be in approximate parallelism with the walls ofA fWhen the radiator is full of water the in- .l

dicating mechanism will be in the position shown in Figs. l and 2 with the float at its highest point. In such position the iexible member is wound upon the drum 13. As soon as the water in the tank falls to a lower level the Hoat will descend communicating such movement to the drum and through the pinion on its spindle to the gear 17 which is mounted on the shaft carrying the indicating hands. As has been before stated, the drum is so 4mounted within the housing that no portion of the iiexible member is in contact -with the. tube in which the flexible member moves and hence there is no danger /of any friction in the movement of the parts.

By providing the indicator with two faces the operator ofthe machine is quite certain to note the condition of his radiator if not when he enters his garage and faces the front of the-machine then most4 certainly ,when he enters the car to drive it.

I claim 'as my invention.:

In combination with a tank having an inletI opening and a capfor closing such opening, said cap -having a centrally disposed aperture, a device for indicating the level of the fluid in said tank including a vertically disposed tube fitted in the aperture of said cap, a housing at the upper end of sai'd'tube, front and rear dialsin said housing, a 'shaft having its bearings in said dials, an indicator hand 'onveach end of said iblef member being secured to said e drum,A

shaft, a gear fixed to said shaft, a drum and and a spring connected to said drum for a spindle therefor rotatably mounted betaking up slaokin said exibie member as 10 tween said dials; a pinion 0n said spindle said oat is raised. l n 5. meshing with said gear, a oat, a flexible x In testimony whereof I have signed this member secured to said float and passing specification.. l.
